The iconic Chris Cornell will be celebrated by the top names in music for a tribute concert in Los Angeles Wednesday night. Less than a day before the show, huge names have been added to the list.

Queens of the Stone Age frontman Josh Homme, Fiona Apple, and Chris Stapleton joined the line-up, as did Brandi Carlile, Miguel, and Miley Cyrus. The Melvins will also perform especially with the surviving members of Soundgarden.

The existing lineup includes Foo Fighters, Ryan Adams, Metallica, Tom Morello, and Cornell’s former bands Audioslave and Temple of the Dog. The “I Am the Highway” tribute concert will be hosted by Jimmy Kimmel at The Forum. Brad Pitt, Tom Hanks and Rita Wilson, David Spade, Kaley Cuoco, Josh and Kathryn Brolin, Matt Cameron, and many more make up the host committee.

“We are honored to have all these amazing artists and friends come together to pay tribute to and show their love and appreciation for Chris, his music and the mark he’s left on the world,” Vicky Cornell said in a statement. “We look forward to sharing this night with all the fans.”
